CNC Machining Vs. CNC Rapid Prototyping

by Anne Zavala

Prototype imitation made lots of progress in the past. However, you can see certain differences between the various types of prototyping. This has raised questions amongst the people supporting rapid CNC prototyping and CNC machining, making them focus more on their technical benefits.

In the initial stages, rapid prototyping tends to exhibit benefits in its speed but then other areas that it ought to develop are constantly halted issues relating to materials and accuracy function. CNC on the other hand has its downsides. In this article, you will find out the ways CNC rapid prototyping and CNC machining are different from each other.

Difference Between CNC Rapid Prototyping and CNC Machining

1. Dimension

The large dimension of getting the parts process is one of the problems of RP and CNC. For RP, the maximum dimension is 600 x 900 x 500 millimeters. Even though the prototype existing may not be used to manufacture a lot of industrial products and general merchandise.

If the parts that will be manufactured by the equipment are many, its other parts can be manufactured first and then joined to make a full part. You must note that the scale determines the time and it may take a long time to create bigger parts.

2. Materials

In rapid prototyping, skills are often hindered to some extent. The research on how to process raw materials has been going on for a while. The scale used for measuring materials has increased and its function is also ensured.

Recently, you can only find ceramic, metals, composite materials, plastic, and other types of materials that have been withheld. Also, the functions of lots of the raw materials do not correspond with the pouring, processing, and molding of materials. CNC Machining on the other hand is free of all constraints. Here, you can cut all raw materials.

3. Scale

The most widely used type of prototyping is CNC Machining. It can be used to manufacture aircraft parts, modules, and practical parts. These may range from the bridge to desktop equipment. Usually, it’s said that the CNC scale constraints are taken from certain mechanical items used.

For rapid prototyping, the level of clutter when processing the parts. The level of clutter in rapid prototyping is mostly unrestricted. This means that if you mold a sample with design software, the cost or production time of the product will not be affected. The biggest benefit of Rapid prototyping is the quick and cheap way of producing messy parts.

Nonetheless, CNC machining is what you need to deal with most of the details of a component. If the clutter of parts gets added, there will be a change and increase in the amount of equipment needed. The cost of CNC cutting tools will be increased by Deep groove, large aspect ratio, and deep hole.


Rapid prototyping and CNC machining are gradually becoming the major methods of manufacturing, in industrial production. Knowing and understanding the differences between will help you if you’re in the manufacturing industry.
